ZOOM
(general link: https://zoom.us)
“See”
you in class starting 7:05pm (Tues. and Thurs.) on Zoom! Check my email for the
class link. See my syllabus for details.
YOUTUBE
You
can access my YouTube channel here; I plan to play these videos during class
time using Zoom - and I can take questions:

CANVAS
I
don’t do much with Canvas, but a student discussion board and a NetTutor link are there. I will email grade information.

ALEKS Extra Credit
(This review can especially help with the very
difficult Chapter 0.)
YOU
CAN PAY FOR AN ALEKS LICENSE. http://www.aleks.com
I
CAN SEND YOU A CLASS CODE. Email me

IF
YOU LIKE ALEKS, BUT YOU FIND THE PACE IN 141 TO BE TOO FAST, TRY THE MATH 15s!
These are great, 1-unit, online, ALEKS-based,
self-paced refreshers that have helped many students. 15E is trig; 15F is
college algebra. A No-Pass grade does not affect GPA, though it does appear on
your transcript; it can be a problem if you are on academic probation. 15E
includes 15D (geometry). Instead of enrolling in both 15E and 15F, contact the
instructor, and they may be able to make arrangements
with you to just enroll in one Precalculus class, though you may be facing
material you have not seen yet.
These are offered at different times throughout the
semester. You could take more than one in one semester! Get a good foundation
for your classes!

Printing Suggestions for Typed Files
I recommend two-page-to-a-side and/or double-sided printing to
save paper. Color printing is nice, but B&W printing is cheaper.
These
are pdf files. You can get the free Adobe Reader at http://www.adobe.com. Get a version that is
compatible with your system!

Class Notes
Many
students benefit from printing the notes for a lecture beforehand, reviewing
them, and commenting on them in class.
You
may want to take personalized sketch notes in class.

simply mention my name and/or web URL somewhere if you are using huge chunks of

Corrections: (0:48-1:07) The double-nappe cone (or simply cone here should not be thought of as finite, so there are no bases nd there is no base perimeter. The term directrix is used elsewhere, especially when describing parabolas.
In
previous semesters, the final was cumulative. For your information, here was
